HelloPharmacist Scorecard of MCT Pure 1,000 mg by Swanson Ultra

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • “Medium-Chain Triglyceride Oil” is listed as a grouped ingredient — the label gives one combined amount (1 Gram(s)) without saying how much of each component you get.

MCT Pure contains 2 active ingredients: caprylic acid and capric acid — both medium-chain fatty acids that your body can use for quick energy. The product is delivered in a softgel capsule made with gelatin, glycerin, and purified water as inactive ingredients.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Caprylic Acid product and its label doesn't state a use — see Caprylic Acid's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold for caprylic acid doesn't establish its effectiveness. Studies rate it as having insufficient reliable evidence for epilepsy and essential tremor.

We have no effectiveness data on file for capric acid.

The evidence, ingredient by ingredient Caprylic Acid

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Caprylic acid is generally recognized as safe when eaten in food, but supplement doses haven't been studied as thoroughly, so the safety data is thinner than we'd like. When taken by mouth, it's generally well tolerated in the short term.

The most common side effects reported are mild stomach discomfort and a change in how things taste. A small number of people have reported mild dizziness, headache, or fatigue.

Because caprylic acid does occur naturally in breast milk, concentrated supplement doses during breastfeeding aren't well understood — talk with your doctor or pharmacist about whether this is right for you if you're nursing.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Caprylic Acid.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 262 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, check with your doctor or pharmacist if you take any blood thinners like warfarin, blood pressure medications, or nonsteroidal anti-inflammatory drugs (NSAIDs). The ingredient caprylic acid may theoretically affect how your body handles these drugs, though these interactions haven't been confirmed in humans.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is a source of medium-chain fatty acids, but we don't have strong evidence it works for any particular health condition. The main caution is if you take a blood thinner, blood pressure medication, or NSAID — check with your doctor or pharmacist first to see whether it's safe for you.

If you're pregnant or breastfeeding, talk it over with your healthcare provider.

MCT Pure 1,000 mg by Swanson Ultra: Common Questions

Does MCT Pure 1,000 mg by Swanson Ultra interact with any medications?
Yes. Based on its ingredients, MCT Pure 1,000 mg has a known interaction with 262 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
MCT Pure 1,000 mg contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What is MCT, and what does it do?
MCT stands for medium-chain triglyceride — a type of fat your body can absorb and use relatively quickly for energy. This product contains two of them: caprylic acid and capric acid. We don't have established evidence in our data that either one treats a specific condition, but they're a dietary source of these fats.
Are there any common side effects?
Caprylic acid is generally well tolerated when taken by mouth. The most common reported side effects are mild stomach discomfort and a change in taste. A small number of people have reported mild dizziness, headache, or fatigue.
Is this safe if I'm pregnant or breastfeeding?
Caprylic acid does occur naturally in breast milk, but the safety of concentrated supplement doses during pregnancy and breastfeeding isn't well established in the data we hold. Talk with your doctor or pharmacist about whether this product is right for you in these situations.
I'm on a blood thinner — can I take this?
That's a conversation for your doctor or pharmacist. Caprylic acid in this product may theoretically increase warfarin levels in your blood, which could affect bleeding risk, though this hasn't been seen in actual patients. Your provider knows your full picture and can advise.
Does it contain any fillers?
The capsule itself is made with gelatin, glycerin, and purified water. Those are the inactive ingredients — the working ingredients are the caprylic and capric acids.
What's capric acid, and how much is in here?
Capric acid is another medium-chain fatty acid similar to caprylic acid. We don't hold interaction or effectiveness data for it specifically. The product label lists both ingredients, but the exact amount of each isn't provided in the facts we have.
